Applications of M2M Communications

It's easy to see why machine-to-machine communications have
so many applications. With better sensors, wireless networks
and increased computing capability, deploying an M2M makes
sense for many sectors.

Utility companies, for instance, use M2M communications, both
in harvesting energy products, such as oil and gas, and in
billing customers. In the field, remote sensors can detect
important parameters at an oil drill site. The sensors can
send information wirelessly to a computer with specific
details about pressure, flow rates and temperatures or even
fuel levels in on-site equipment. The computer can
automatically adjust on-site equipment to maximize
efficiency.

Traffic control is another dynamic environment that can
benefit from M2M communications. In a typical system, sensors
monitor variables such as traffic volume and speed. The
sensors send this information to computers using specialized
software that controls traffic-control devices, like lights
and variable informational signs. Using the incoming data,
the software manipulates the traffic control devices to
maximize traffic flow. Researchers are studying ways to
create M2M networks that monitor the status of
infrastructure, such as bridges and highways.

Telemedicine offers another use. For instance, some heart
patients wear special monitors that gather information about
the way their heart is working. The data is sent to implanted
devices that deliver a shock to correct an errant rhythm.

Business also can use M2M communications for tracking
inventory and security. Late in 2007, M2M communications
helped break up a heavy equipment theft ring. A rental
company noticed sensors on its equipment showed the
bulldozers were almost 100 miles from where they were
supposed to be. Checking on other equipment rented the same
day at different locations showed a similar trend, and the
business used its M2M communications to disable the engines
on the equipment and contacted law enforcement. Officers
found that the company's equipment, along with a dozen other
stolen pieces, were headed for the Mexican border.

Machine-to-machine communication appears to have a bright
future. It's a flexible technology that uses common equipment
in new ways. Every day, businesses, engineers, scientists,
doctors and many others are finding new ways to use this new
communications tool.
